Abstract

A pulse abnormality detecting device comprises a band attached to a wrist, a first sliding member with which the band is armored and which slides in the circumference direction of the band along the band, a second sliding member which is slidably provided on the first sliding member and which slides in the axis direction of the band, a pulse sensor which is provided on the second sliding member and which is provided in such a manner that the position of the sensor can be adjusted to the inner side or the side of the band, and a pulse abnormality detecting unit for detecting the abnormality of the pulse from the output data of the pulse sensor. The device can accurately detect the pulse of a user with high precision, adapting to a personal difference.

Claims

1. A pulse abnormality detection apparatus comprising:

a band worn around a wrist or an arm;

a pulse sensor provided inwardly or laterally of the band; and

a pulse abnormality detector for detecting a pulse abnormality from data outputted from the pulse sensor, wherein the pulse sensor is provided so that its position is adjustable.

2. The pulse abnormality detection apparatus according to claim 1, the apparatus comprising:

a storage module for storing a standard pulse waveform and a set value by which a pulse allowable range is defined; and

a pulse abnormality recognition module for making a comparison between an output waveform, which is data outputted from the pulse sensor, and the standard pulse waveform, and for recognizing an abnormality when results of the comparison include a value falling outside the allowable range defined by the set value, wherein the pulse abnormality detector is formed by the storage module and the pulse abnormality recognition module.

3. The pulse abnormality detection apparatus according to claim 1, wherein the pulse sensor is provided so as to be movable in a circumferential direction of the band and in an axial direction of the band.

4. The pulse abnormality detection apparatus according to claim 3, the apparatus comprising:

a first slide body that is externally attached to the band and that slides along the band; and

a second slide body that is slidably provided at the first slide body and that slides in the axial direction of the band, wherein the second slide body is provided with the pulse sensor.

5. The pulse abnormality detection apparatus according to claim 1, wherein the second slide body has elasticity by which the pulse sensor is urged inwardly of the band, or an elastic member, by which the pulse sensor is urged inwardly of the band, is provided between the second slide body and the pulse sensor.

6. The pulse abnormality detection apparatus according to claim 5, wherein the elastic member is a pressure sensitive diaphragm.

7. The pulse abnormality detection apparatus according to claim 4, wherein a tip of the second slide body is provided with a fixation member having a shape substantially conforming to at least part of a circumference of the wrist or that of the arm, or a fixation member deformable into the shape.

8. The pulse abnormality detection apparatus according to claim 1, wherein the band is provided with a main body, and the main body is provided with the pulse abnormality detector.

9. The pulse abnormality detection apparatus according to claim 1, wherein the band is provided with a transmitter, a receiving terminal is provided with the pulse abnormality detector, and an output waveform, which is data outputted from the pulse sensor, is transmitted to the receiving terminal via the transmitter.

10. The pulse abnormality detection apparatus according to claim 2, wherein the pulse sensor is provided so as to be movable in a circumferential direction of the band and in an axial direction of the band.

11. The pulse abnormality detection apparatus according to claim 2, wherein the second slide body has elasticity by which the pulse sensor is urged inwardly of the band, or an elastic member, by which the pulse sensor is urged inwardly of the band, is provided between the second slide body and the pulse sensor.

12. The pulse abnormality detection apparatus according to claim 3, wherein the second slide body has elasticity by which the pulse sensor is urged inwardly of the band, or an elastic member, by which the pulse sensor is urged inwardly of the band, is provided between the second slide body and the pulse sensor.

13. The pulse abnormality detection apparatus according to claim 4, wherein the second slide body has elasticity by which the pulse sensor is urged inwardly of the band, or an elastic member, by which the pulse sensor is urged inwardly of the band, is provided between the second slide body and the pulse sensor.

14. The pulse abnormality detection apparatus according to claim 5, wherein a tip of the second slide body is provided with a fixation member having a shape substantially conforming to at least part of a circumference of the wrist or that of the arm, or a fixation member deformable into the shape.

15. The pulse abnormality detection apparatus according to claim 6, wherein a tip of the second slide body is provided with a fixation member having a shape substantially conforming to at least part of a circumference of the wrist or that of the arm, or a fixation member deformable into the shape.

16. The pulse abnormality detection apparatus according to claim 2, wherein the band is provided with a main body, and the main body is provided with the pulse abnormality detector.

17. The pulse abnormality detection apparatus according to claim 3, wherein the band is provided with a main body, and the main body is provided with the pulse abnormality detector.

18. The pulse abnormality detection apparatus according to claim 4, wherein the band is provided with a main body, and the main body is provided with the pulse abnormality detector.

19. The pulse abnormality detection apparatus according to claim 2, wherein the band is provided with a transmitter, a receiving terminal is provided with the pulse abnormality detector, and an output waveform, which is data outputted from the pulse sensor, is transmitted to the receiving terminal via the transmitter.
